Title: Control method of air-fuel ratio
Inventor: MATSUMURA TOSHIMI
IPC: F02D41/02
Filed: 1981-04-07
Abstract: PURPOSE: To reduce a change factor at learning correction in air-fuel ratio control of a mixture with a recovery vaporized component, by controlling a feed amount of the vaporized component to an engine from a fuel recovery means in accordance with an operational condition.  
     CONSTITUTION: A signal of air-fuel ratio sensor 14 is integrated in a central processing unit (CPU)100, on the basis of its integration correction, calculated and stored as a correction amount of engine condition correspondingly to its operational condition, then air-fuel ratio is controlled by the both correction amounts. At starting, a previously stored engine condition correction amount is checked, if exceeding a limit value, the correction amount is reset to a prescribed value. Accordingly, at transient or sensor inactive time when feedback control can not be performed, air-fuel ratio can be accurately controlled. Further to decrease a change factor of the engine condition at learning correction operation, vaporized fuel in a fuel tank is not fed by closing a solenoid valve 33, and the air-fuel ratio can be high accurately controlled.

Title: Multicycle throttle working method for automatic spinning working machine
Inventor: YASUTOMI SHIYUNICHI
IPC: B21D22/18
Filed: 1981-04-07
Abstract: PURPOSE:To facilitate an easy fine adjustment of the throttle working and to simplify a device as a whole, by securing an optional adjustment for the throttling degree of the multicycle working by the external signal. CONSTITUTION:A throttle roller R is first pressed at a prescribed center position to a material W1 which is cut into a prescribed length to carry out the throttle working. In this case, the roller R is shifted by the signal supplied from an auxiliary gauge B. The gauge B decides the movement of the roller for the throttle working to ensure the effective drawing function, and the throttling degree is reduced based on the right line. The external signal is applied also to a hydraulic servo mechanism. In case the external signal is applied for the continuous advance, the roller shifts along a shift line having an inclination slightly slow than the line along the gauge B synthesized by both signals. When a limit switch LS1 touches an auxiliary dog D, a throttle stand is reset. Then a limit switch LS2 provided to the throttle stand touches a finishing dog C to switch again to the advancing direction of the throttle stand.

IPC: F28G9/00
Filed: 1997-03-07
Abstract: PROBLEM TO BE SOLVED: To prevent recirculation of foreign matters while eliminating count error of cleaning matters at the time of constant collection by passing foreign matters and cleaning matters through a foreign matter crushing roller, separating them by the difference of specific gravity, discharging the foreign matters to the outside of the system and feeding the cleaning matters to a counter. SOLUTION: A foreign matter/cleaning matter inlet pipe 1 is coupled with a cleaning matter catcher and cleaning matters 10 used for cleaning the thin tubes of a condenser is collected and fed through the foreign matter/cleaning matter inlet pipe 1 in order to crush the foreign matters through a foreign matter crushing roller 2 disposed at the inlet of a foreign matter crushing/ separating chamber 4. Crushed foreign matters 9 and the cleaning matters 10 are received by a foreign matter/cleaning matter separating grid 3 through which the foreign matters are passed downward and discharged through a foreign matter outlet pipe 6 to the outside of the system. The cleaning matters 10 flow along the grid 3 and introduced through a cleaning matter outlet pipe 7 toward a counter.  Since the foreign matters 9, e.g. shells, are separated from the cleaning matter 10 and only the cleaning matters 10 are counted, reliability of count is enhanced while eliminating recirculation of sea organisms.

Further, the water intake pipe 42 is rendered detachable from the joint body 12, which facilitates cleaning for removing dirt accumulated in the joint body 12. Still further, the water intake gutter joint is connected to an intermediate portion of a down pipe connected to an eaves gutter. A water intake pipe of the water intake gutter joint is connected to an upper end of a connecting conduit, and a lower end of the same is connected to a water storage tank, to thereby constitute a water collecting system. Thus, handling and cleaning of the water intake gutter joint are facilitated, and rainwater flowing through the down pipe can be taken in and introduced into the water storage tank.

Title: Automatic gain control method of light communication system
Inventor: NISHIMOTO HIROSHI
IPC: H04B10/564
Filed: 1980-04-23
Abstract: PURPOSE:To greatly improve the effect of S/N by switching the all AGC to the electrical AGC before S/N of APD is saturated, and raising the light input level in case a factor for deterioration of S/N has been caused. CONSTITUTION:An optical signal Sin is photoelectrically converted and also is amplified by the APD 1 having photoelectric current multiplication factor M. Also, an output of the APD1 is amplified by the amplifier 2 having gain G, and an output Sout of almost constant level can be obtained. In this case, when the output of the APD1 is in a low level, the gain G of the amplifier is made constant by the AGC circuit, and the photoelectric current multiplication factor M of the APD1 is varied. The minimum value of M is set, for instance, to Mmin.=8, by which saturation of S/N is suppressed. Accordingly, in case of M=Mmin., when the output of the  APD1 becomes a high level, the all AGC is switched to the electrical AGC, which  controls so that the gain G of the amplifier 2 is decreased.

Filed: 1998-03-05
Abstract: PROBLEM TO BE SOLVED: To facilitate working machine housing operability by determining a housing position by mechanical positioning based on the respective stroke ends of a first boom hoisting cylinder rod, a second boom hoisting cylinder rod and a working arm hoisting cylinder rod. SOLUTION: When a two-piece boom working machine is folded and housed within the turning radius of a revolving superstructure 3, it is so set that a position determined by the operating stroke end of each of boom hoisting cylinders 6, 8 is a housing position within the turning radius. The position of a second boom 7 is determined limiting to such a second boom hoisting cylinder stroke that the second boom 7 does not bend down lower than the nearly horizontal posture even if operation of bending-down action is applied to the second boom 7 in the state of a first boom 5 being positioned upward at a rear half part of the revolving superstructure 3. The stop position of hoisting cylinder action of the respective booms 5, 7 is therefore the storage position within the turning radius of the revolving superstructure 3. The working machine can therefore be housed within the turning radius so as to improve housing operability.
